T 0 aZZ whom it may concern: 1

Be it known that I, Gnovnn C. HEN- nnIoKs, a citizen of the United States, and resident of Dugger, in the county of Sullivan and State of Indiana, have invented certain new and useful Improvements in Carbid- Lamps, of which the following is a specification. 7

' I This invention relates to improvements in carbid lamps and the invention has for its dominant object to provide a carbid lamp in whichthe cooperating gas generating parts are arranged within a supporting base, thus protecting the same and also affording an extremely compact and ornamental construction'. 1 7

Another object of theinventionis to provide'novel water discharge means for supplying water to the carbid chamber of the lamp construction. y Other and further improvements and novel details in the construction and arrangement of parts will be appreciated from the description to follow, which, for a clear understanding of the invention should be considered in connection with the accompanying drawings forming a part hereof and wherein the preferred embodiment of the invention is shown for the purpose of illustration.

In the drawings;

Figure 1 is a vertical section through the improved carbid lamp, and a.

Fig. 2 is a horizontal section therethrough taken on the line 2+2 of Fig. 1.

Similar characters of reference are employed in all of the above-described views to indicate corresponding parts.

Referring now more specifically to the several figures of the said drawings, a hollow supporting base 1 is provided the lower portion of which is formed to constitute a pedestal or stand 2, while the upper portion thereof, as will be noted in the Fig. 1, is

open. V p

A water containing. receptacle 3 is provided and has the upper portion thereof formed with a laterally extending annular lip 4 adapted to be engaged with the upper marginal edge of the supporting base 1 in order that the said receptacle 3 may be efficiently supported therein. 'i\ filling opening is formed within the top of the water receptacle 3 and is normally closed by means of a screw cap ,5 turned into engagement Specification of Letters Patent.

therewith. To permit the flow of water from the receptacle 3 a neck 6 is engaged with the bottom thereof and has its free extremity braced by means of a metal strap 7 arranged thereabout. A valve stem 8 is passed downwardly through the water receptacle 3 and carries a valve 8f at its lower end which is adapted to be arranged over the open end of the said neck, at times, for an obvious purpose. To render the receptacle fluid tight, a packing. gland 9 is arranged within the. receptacle bottom and receives the said valve 8 therethrough.

A gas discharge conduit 10 extends through the water receptacle 3 and opens onto the bottom thereof to permit the discharge of gas from the generating chamber into the same from where it is conveyed to the burner 11 arranged upon the upper end thereof. Filtering material 12 may be and preferably is arranged adjacent the open lower end of the conduit 10.

Upon the under face of the water receptacle bottom there isarranged an internally screw threaded collar 13 adapted to receive therein a similarly threaded collar 14 formed upon a lid member 15 which turns into engagement with the open upper ex tremity of a carbid receptacle 16.

r The usual chimney holder 17 is arranged upon the top portion of the water receptacle 3 about the burner 11 and carries thereon springs in the engaging fingers 18.

In operation, the carbid receptacle 16 is filled and engaged withthe screw threaded collar 13 of the water receptacle 3 thereupon the said receptacles are placed within the hollow supporting base 1, the annular-lip 1 engaging with the upper marginal edge of the said base and serving to support the same in proper position thereupon. By regulating thevalve 8, water will be permitted to flow from the discharge neck 6 into the carbid receptacle 16 and as a result, gas will be generated and conveyed by the conduit 10 to the burner 11 whereat it is ignited.

This assembling of the cooperating parts of the gas generating apparatus of the lamp will be readily permitted due to their positioning within the hollow supporting base 1. Further, repairing to any part thereof can be readily done.

It is to be understood that the lamp is not to be limited in its use by slight variations in the construction thereof and, can be used as a hand lantern, vehicle lantern, mining H lamp, house lamp, etc.,such as conditions or preference may dictate. V

Manifestly the construction shown is capable of considerable modification the, carbld receptacle, a Water pipe communlcatlng With the Waterreceptacle, extending such modification as is Within the scope of my claims I consider Within the spirit of my 7 reptacle 'and provided with an upwardly directed discharge terminal arranged in the '20 invention.
